Incorrect logic related to hover/click events

[frewsxcv]

I got an email from someone who is using the library. They're reporting the logic related to hovering/clicking on nodes is incorrect. Here's what they wrote:

---

the node ids that are returned refer to the
THREE.BufferGeometry node and not the Graph Node nodes.
Hence the label will always be incorrect.

I added a BufferAttribute to the BufferGeometry to map back to the
Graph Node ids.

Frame.prototype._syncNodeDataFromGraph = function () {
var nodes = this.graph.nodes();

    var positions = new THREE.BufferAttribute(
        new Float32Array(nodes.length * 3), 3);
    var colors = new THREE.BufferAttribute(
        new Float32Array(nodes.length * 3), 3);
   //id array
   var ids = new THREE.BufferAttribute(
        new Float32Array(nodes.length), 1);

    for (var i = 0; i < nodes.length; i++) {
        var node = nodes[i];
        var pos = node._pos;
        var color = node._color;

        positions.setXYZ(i, this.scale * pos.x, this.scale *
    pos.y, this.scale * pos.z);
        colors.setXYZ(i, color.r, color.g, color.b);

        ids.setX(i, node._id);
    }

    this.points.addAttribute('position', positions);
    this.points.addAttribute('color', colors);
    this.points.addAttribute('id', ids);

    this.points.computeBoundingSphere();

    this._normalizePositions();
    this.positionCamera();
};

and

 Frame.prototype._initMouseEvents = function (elem) {
     ..
            var intersects =
       raycaster.intersectObject(self.pointCloud);
            if (intersects.length) {
                var nodeIndex =
       intersects[0].object.geometry.attributes.id.getX(intersects[0].index);
                callback(self.graph._nodes[nodeIndex]);
